COVID-19 Community Levels Map Update, Jan. 27, 2023: The CDC has listed three Connecticut Counties—Litchfield, Middlesex and New Haven Counties—in the High/Orange category as part of its weekly COVID-19 Community Levels update. Fairfield, Hartford, New London, Tolland and Windham Counties are listed in the Medium/Yellow category.  Because all eight Connecticut counties are either in the High or Medium categories, the Connecticut Department of Public Health recommends that all residents consider wearing a mask in public indoor spaces. People who are at high risk for severe illness should consider additional measures to minimize their exposure to COVID-19 and other respiratory illnesses.

This disease is not spread in Connecticut; however, residents can acquire it by traveling to foreign endemic areas. Outbreaks have occurred in Africa, Asia, Europe, areas of the Indian and Pacific Oceans, Central and South America, and the Caribbean. In Connecticut, surveillance is conducted to identify travel-related cases. There is no vaccine to prevent or medicine to treat chikungunya virus infection. The best way to prevent getting sick from chikungunya virus is to prevent mosquito bites.
